Petrolatum, also known as petroleum jelly, is a semi-solid mixture of hydrocarbons that is widely used in various industries such as cosmetics, pharmaceuticals, and lubrication. It is composed of saturated hydrocarbons and is often used as an ointment or lubricant. Common uses for petrolatum include use as a moisturizer, protectant, antiseptic, and even as a sealant or lubricant.
When rubber is exposed to petrolatum, there are a few common types of failures that may occur. These include hardening and cracking of the rubber material, swelling of the rubber, and embrittlement of the rubber due to the chemicals leaching out of the material. Additionally, there may be a decrease in the rubber's tensile strength and elongation properties, which can lead to premature failure of the rubber seal.
